Zelensky says Ukraine will not give up land

Volodymyr Zelensky has ruled out surrendering Ukrainian land to Russia, as Donald Trump and Vladimir Putin prepare to meet next week. In a video address, President Zelensky said any decisions taken without Ukraine would be -- as he put it -- dead decisions. Mr Trump has talked of Russia and Ukraine swapping territory. Several Ukrainian civilians have been killed during another night of aerial attacks by Russia.
